There are cases where being honest leads to discrimination.

Like every situation in life ever?

Practicality anything that I disclose will shift someone assessments of me on some metric or another, and from what we know of status assessment and things like the halo effect we can infer this is almost never neatly contained. I don't quite see how in principle selective dishonesty in the form of disclosing information that improves my standing rather than hurts it is anything but typical human behaviour. Sure one can argue that its justified only for when I have good reason to believe what I disclosed would be used to judged unfairly.

But all people tend to view any heuristics that can discriminate against them as baseless and unfair.
